Top 6 Best Saltwater Fish for 5-Gallon Nano Tanks | PNW Tiny Tank Guide | Hilary Jaffe

03-31-2026 Finding the right livestock for a nano or pico aquarium can be a challenge, as most research suggests a 10-gallon minimum for even the smallest species. In this episode, Hilary breaks down six perfect saltwater fish candidates that stay small enough to thrive in a 5-gallon "Small In One" system. From the vibrant Neon Goby and the symbiotic Yasha Goby to the personality-packed White-Spotted Pygmy Filefish, we explore unique fish that offer incredible colors and fascinating behaviors without outgrowing their habitat. Whether you're interested in the "busybody" Barnacle Blenny or the hardy Gumdrop Coral Crusher, this guide helps you choose reef-safe inhabitants that make your tiny tank the star of the show. ______________________________________________ ⚠️ Products In This Video ► PNW Custom Glass Small-In-One XL 5 Gallon Desktop Aquarium - https://www.saltwateraquarium.com/glass-small-in-one-xl-5-gallon-desktop-aquarium-pnw-custom/ ► ORA Captive-Bred Neon Goby - https://www.saltwateraquarium.com/arag-alive-special-grade-reef-sand-10-lb-1-0-2-0-mm-caribsea/ ► ORA Captive-Bred Whitespotted Pygmy Filefish - https://www.saltwateraquarium.com/captive-bred-whitespotted-pygmy-filefish-rudarius-ercodes-ora/ ► Caribsea LifeRock Dreamscapes Assortment (5-15 Gallon Tank) - https://www.saltwateraquarium.com/liferock-dreamscapes-assortment-5-15-gallon-tank-caribsea/ ► Caribsea Arag-Alive Special Grade Reef Sand (10 lb) 1.0 - 2.0 mm - https://www.saltwateraquarium.com/arag-alive-special-grade-reef-sand-10-lb-1-0-2-0-mm-caribsea/ ► Eheim 25 Watt Jager TruTemp Submersible Aquarium Heater - https://www.saltwateraquarium.com/25-watt-jager-trutemp-submersible-aquarium-heater-eheim/ ______________________________________________ Website - https://www.saltwateraquarium.com Follow us on Facebook - https://www.facebook.com/swaqdotcom/ Follow us on Instagram - https://www.instagram.com/saltwateraquariumdotcom/ Follow us on TikTok - https://www.tiktok.com/@saltwateraquarium.com ______________________________________________ 📩 If you have a request related to equipment in this video, or this video in general, email - [email protected] #saltwateraquarium #swaq
